I have not read the comics, so I would understand if this is answered later.
Why won’t Viltrum send one or two soldiers to Earth to subjugate it after finding out about Omni Man’s desertion? Why are they even bothering with getting Mark to do it when they have so many seasoned and ruthless soldiers who are more than capable of finishing the job?
I get that they can’t be everywhere at once, but can they really not send one or two over?
My theory was that they dont have enough men for that, and maybe Earth is not worth the effort given that they deal with a coalition against them and are shortstaffed.
